中文摘要：

本文将线性疲劳累积损伤理论分为3类：（1）等损伤线性疲劳累积损伤理论;（2）变损伤线性疲劳累积理论;（3）等损伤线性分阶段疲劳累积损伤理论.对每类理论分别从理论基础、材料常数、引入的参量及工程应用等方面进行分析,归纳出典型模型,并利用金属材料的两级谱、多级谱和随机谱试验数据进行了评估.最后,从理论基础和数据评估两方面进行综合评述,得出了不同类型的模型的适用范围和计算效果,对工程实践具有参考价值.

英文摘要：

The fatigue accumulative damage theories for metal materials can be divided into the following three categories：（1） linear cumulative damage theories of invariable damage;（2） linear cumulative damage theories of variable damage;（3） periodical linear cumulative damage theories of invariable damage. They are reviewed in this paper with respect to their theoretical bases, material constants, parameters involved,engineering applications and major typical models. Besides, several sets of variable loading tests of metal materials under a two-level spectrum, a multiple-level spectrum and a random spectrum are used to verify the major typical models. Finally, the applicable scopes and applications of the above three kinds of accumulative damage rules are compared and discussed according to their theoretical basis and the accuracy rate.
